Description

Technical Field

[0001] The present invention relates to the technical field of tunnel or underground construction equipment, in particular to a universal rod library for drill and anchor rods. Background Art

[0002] During tunnel or mine construction, drilling is often necessary for excavation or anchor bolting to prevent water leakage, rock leakage, or collapse. Deep hole drilling requires connecting rods to reach the desired depth. Similarly, anchor bolting requires connecting rods to reach the desired position.

[0003] In the prior art, drill rods and anchor rods are each mounted in a rod magazine within the propulsion mechanism of the corresponding mechanical equipment to achieve drilling and anchor support, respectively. These two rod magazines are bulky, making it difficult for both machines to operate simultaneously in a confined space. However, the existing universal rod magazines for both drill and anchor rods are bulky, have numerous actuators, and are heavy, making them unsuitable for anchor rod magazines. While the anchor rod transfer mechanism is compact and lightweight, it cannot achieve the reciprocating or swinging functions of the drill rod magazine, resulting in the incompatibility of drill and anchor rod magazines.

[0004] Chinese patent application CN201963224U discloses a disc-type drill rod magazine suitable for medium-deep hole connecting rod drilling, including a manipulator and a locker, wherein the manipulator is composed of two cylinders and multiple mechanical arms, and the locker is composed of an oil cylinder and a mechanical arm. There are many actuators and the structure is relatively complicated, resulting in large size and heavy weight.

[0005] Therefore, there is an urgent need for a universal drill and anchor rod library that can make the drill rod library and the anchor rod library universal. Summary of the Invention

[0007] In view of the above shortcomings and deficiencies of the prior art, the present invention provides a universal rod library for drill and anchor rods, which solves the technical problem that the drill rod library and the anchor rod library cannot be used interchangeably due to the large volume and weight of the universal rod library for drill and anchor rods.

DETAILED DESCRIPTION

[0047] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 2For reference, the axial direction of the transmission shaft 42 is defined as the "front-rear direction", and the end close to the linkage rod 414 is defined as the "front".

[0048] Example

[0049] like Figures 1 to 7 As shown, a universal rod storage for drill and anchor rods comprises a fixed frame 1, a placement mechanism, and a rotation mechanism 4. The fixed frame 1 is mounted on a propulsion beam 6. The placement mechanism is used to place rods 7 and is rotatably mounted on the fixed frame 1. The placement mechanism is a rotating body capable of rotating about its axis. The rotation mechanism 4 comprises a support frame 41, a transmission shaft 42, and two rotation mechanisms. The support frame 41 is fixed to the propulsion beam 6. One end of the transmission shaft 42 is rotatably mounted on the support frame 41, and the other end is in transmission connection with the placement mechanism. The two rotation mechanisms are mounted side by side on the transmission shaft 42 and can intermittently rotate about the transmission shaft 42 in opposite directions. At any given time, only one of the two rotation mechanisms rotates. The two rotation mechanisms can respectively drive the transmission shaft 42 to intermittently rotate in opposite directions about its axis, thereby rotating the rods 7 on the placement mechanism or the placement slot of the placement mechanism to a predetermined position. The two rotation mechanisms are arranged side by side, meaning that the axes of both rotation mechanisms coincide with the axis of the transmission shaft 42, i.e., the two rotation mechanisms are arranged side by side in the front-to-back direction.

[0050] In the prior art, drill rods and anchor rods are each installed in a rod magazine on a corresponding propulsion mechanism to achieve drilling and anchor support, respectively. These two rod magazines are large, and in a narrow space, the two machines cannot operate simultaneously. However, the prior art universal rod magazine for drill and anchor rods is bulky, has many actuators, and is heavy, making it unsuitable for an anchor rod magazine. The anchor rod transfer mechanism 4 is small and light, but cannot achieve the reciprocating or swinging functions of the drill rod magazine, resulting in the drill rod magazine and the anchor rod magazine not being compatible.

[0051] The present invention uses two rotating mechanisms to intermittently drive the placement mechanism to rotate, so that the rod 7 or the placement slot of the placement mechanism rotates to a preset position. Compared with the prior art, the present invention only needs two rotating mechanisms to drive the placement mechanism to rotate intermittently. It has a simple structure, small size, and light weight. It can be used on both drill rod magazines and anchor rod magazines, so that drill rods and anchor rods can share one rod magazine.

[0052] An arc-shaped retaining ring is also fixedly mounted on the fixing frame 1 , and the arc-shaped retaining ring is used to limit the radial direction of the rod 7 to prevent the rod 7 from falling.

[0053] like Figures 2 to 6 As shown, the rotating mechanism 4 is a ratchet wheel with multiple ratchet teeth evenly arranged on its circumference, and the ratchet teeth of the two rotating mechanisms 4 are tilted in opposite directions. The rotating mechanism 4 can also be a grooved wheel as long as it can achieve intermittent rotation.

[0054] Specifically, the two ratchets are a forward-rotating ratchet 43 and a reverse-rotating ratchet 44. The forward-rotating ratchet 43 can drive the placement mechanism forward via the transmission shaft 42, while the reverse-rotating ratchet 44 can drive the placement mechanism reverse via the transmission shaft 42, thereby rotating the rod 7 or placement slot placed in the placement mechanism to a predetermined position, thereby facilitating the grasping of the rod 7 or the placement of the rod 7 in the placement slot. The terms forward and reverse rotation are relative and simply refer to two opposite directions of rotation; forward and reverse do not have specific directions. In this embodiment, the reverse-rotating ratchet 44 is located in front of the forward-rotating ratchet 43 as an example.

[0055] like Figures 2 to 6 As shown, the indexing mechanism 4 also includes an active pawl 49 that drives the rotating mechanism to rotate intermittently. The middle part of the active pawl 49 is rotatably connected to the transmission shaft 42 through a swing rod 412, and the active pawl 49 can swing around the connection point between it and the swing rod 412; both ends of the active pawl 49 are provided with pushing claws, and the pushing claws at both ends are respectively placed on both sides of the connection point between the active pawl 49 and the support frame 41, and the pushing claws at both ends respectively drive the two rotating mechanisms to rotate; at the same time, one of the pushing claws at both ends can engage with the ratchet teeth of the ratchet wheel of the corresponding rotating mechanism to drive the corresponding rotating mechanism to rotate.

[0056] like Figure 4 As shown, specifically, in this embodiment, the pushing pawls at both ends are respectively a first pushing pawl 491 and a second pushing pawl 492, which are arranged side by side along the axial direction of the transmission shaft 42. The first pushing pawl 491 corresponds to the reverse ratchet 44 and can engage with the ratchet teeth of the reverse ratchet 44 to drive the reverse ratchet 44 to rotate intermittently in the reverse direction; the second pushing pawl 492 corresponds to the forward ratchet 43 and can engage with the ratchet teeth of the forward ratchet 43 to drive the forward ratchet 43 to rotate intermittently in the forward direction.

[0057] like Figure 5 and 6 As shown, the indexing mechanism 4 also includes two stop blocks, both mounted on the support frame 41. The two stop blocks are respectively used to limit the deflection angle of the corresponding rotation mechanism pushed by the push pawls at both ends of the active pawl 49. The two stop blocks are respectively mounted on both ends of the active pawl 49. Before the push pawl separates from the ratchet teeth of the rotation mechanism, the push pawls at both ends can abut against the two stop blocks. The two stop blocks limit the deflection angle of the active pawl 49. The angle from the initial engagement of the active pawl 49 with the corresponding ratchet teeth of the rotation mechanism to the abutment of the active pawl 49 with the corresponding stop block is consistent with the rotation angle of the placement mechanism from one placement slot to another. Therefore, the active pawl 49 can accurately swing one working position with each reciprocating swing, thereby precisely controlling the rotation angle of the corresponding rotation mechanism to ensure the accuracy of grabbing or placing the drill rod.

[0058] Specifically, the two stop blocks are a first stop block 47 and a second stop block 48. The first stop block 47 is fixedly mounted on the front side of the forward ratchet 43 and is located at the end position of the swing of the second push pawl 492. The second push pawl 492 can abut against the first stop block 47, thereby limiting the position of the second push pawl 492. The second stop block 48 is placed on the rear side of the reverse ratchet 44 and is located at the end position of the swing of the first push pawl 491. The first push pawl 491 can abut against the second stop block 48, thereby limiting the position of the first push pawl 491.

[0059] like Figure 5 As shown, the indexing mechanism 4 also includes a first telescopic driver 45 for driving the active pawl 49 to swing; one end of the first telescopic driver 45 is hinged to the support frame 41, and the other end is hinged to the swing rod 412. The first telescopic driver 45 can be telescopic in the vertical direction.

[0060] like Figure 3 As shown, in this embodiment, a swing lever 412 is sleeved on the transmission shaft 42 and rotatably connected thereto. The telescopic end of the first telescopic actuator 45 is hingedly connected to the swing lever 412. When the telescopic end of the first telescopic actuator 45 is extended or retracted, the swing lever 412 drives the active clamping jaw 49 to deflect, causing the first pushing pawl 491 to rotate the reverse-rotating ratchet 44, and the first pushing pawl 491 deflects and stops when it abuts the second stop block 48; or the second pushing pawl 492 drives the forward-rotating ratchet 43 to rotate, and the second pushing pawl 492 deflects and stops when it abuts the first stop block 47.

[0061] In this embodiment, the first telescopic driver 45 is an oil cylinder, and may also be an air cylinder or a telescopic rod, as long as it can drive the active pawl 49 to swing.

[0062] like Figure 5 and 6 As shown, the transfer mechanism 4 also includes a stop pawl 410, the middle part of which is rotatably connected to the support frame 41, and the stop pawl 410 includes two stop pawls, which can respectively engage with the ratchet teeth of the forward ratchet 43 and the reverse ratchet 44, and are respectively used to prevent the corresponding rotating mechanism from rotating in the opposite direction; when the active pawl 49 pushes one of the rotating mechanisms to rotate, the stop pawl 410 prevents the corresponding rotating mechanism from rotating in the opposite direction, and the other rotating mechanism is relatively stationary with the transmission shaft 42.

[0063] One of the anti-retraction pawls can mesh with the ratchet teeth of the forward ratchet 43, and the other anti-retraction pawl can mesh with the ratchet teeth of the reverse ratchet 44. At the same time, only one of the two anti-retraction pawls is engaged with the forward ratchet 43 or the reverse ratchet 44. Specifically, when the second pushing pawl 492 of the active pawl 49 meshes with the ratchet teeth of the forward ratchet 43, the active pawl 49 pushes the forward ratchet 43 to rotate, and one of the anti-retraction pawls 410 also meshes with the ratchet teeth of the forward ratchet 43, and the pushing pawl and the anti-retraction pawl push the forward ratchet 43 in opposite directions. That is, when the active pawl 49 pushes the forward ratchet 43 to rotate forward, the anti-retraction pawl 410 prevents the forward ratchet 43 from reversing. The transmission shaft 42 rotates forward with the forward ratchet 43, and the reverse ratchet 44 rotates forward with the transmission shaft 42. Similarly, when the active pawl 49 pushes the reverse ratchet 44 to rotate in the reverse direction, the stop pawl 410 prevents the reverse ratchet 44 from rotating forward, the transmission shaft 42 rotates reversely along with the reverse ratchet 44 , and the forward ratchet 43 rotates reversely along with the transmission shaft 42 .

[0064] like Figure 2 As shown, the indexing mechanism 4 also includes a linkage rod 414, each end of which is rotationally connected to the support frame 41 via a rotating shaft, and the middle portion is rotationally connected to the transmission shaft 42. A driving mechanism 411 is mounted on each of the rotating shafts, which drives the corresponding active pawl 49 or the stop pawl 410 to swing. A second telescopic actuator 46 is hinged at both ends to the support frame 41 and the linkage rod 414, respectively. Under the telescopic action of the second telescopic actuator 46, the linkage rod 414 drives the two driving mechanisms 411 to swing, so that the active pawl 49 and the stop pawl 410 both act on the same rotating mechanism. The active pawl 49 and the stop pawl 410 are arranged symmetrically about the center of the forward-rotating ratchet 43.

[0065] like Figure 5 and 6 As shown, specifically, the pushing mechanism 411 includes a connecting seat, which is fixedly mounted on the corresponding rotating shaft, and a first push rod 4111 and a second push rod 4112 are respectively installed on both sides of the connecting seat, and the first push rod 4111 and the second push rod 4112 are arranged at an angle, and the active pawl 49 or the anti-retraction pawl 410 is clamped therebetween. Under the telescopic action of the second telescopic driver 46, the linkage rod 414 drives the two rotating shafts to rotate, and the first push rod 4111 or the second push rod 4112 pushes the corresponding active pawl 49 or the anti-retraction pawl 410 to swing, so that the active pawl 49 and the anti-retraction pawl 410 both act on the same rotating mechanism.

[0066] The two pushing mechanisms 411 are respectively a first pushing mechanism for pushing the active pawl 49 and a second pushing mechanism for pushing the anti-retraction pawl 410. The first push rod 4111 of the first pushing mechanism is attached to the outside of one pushing pawl of the active pawl 49, and the second push rod 4112 of the first pushing mechanism is attached to the outside of the other pushing pawl of the active pawl 49. The first push rod 4111 of the second pushing mechanism is attached to the outside of one anti-retraction pawl of the anti-retraction pawl 410, and the second push rod 4112 of the second pushing mechanism is attached to the outside of the other anti-retraction pawl of the anti-retraction pawl 410. The outside refers to the side away from the active pawl 49. In this embodiment, the first push rod 4111 and the second push rod 4112 are both leaf springs.

[0067] During use, the telescopic end of the second telescopic actuator 46 extends and retracts, driving the linkage rod 414 to swing about the transmission shaft 42. The linkage rod 414 drives the corresponding pushing mechanism 411 to swing via two rotating shafts, causing the pushing mechanism 411 to push the corresponding active pawl 49 or the anti-retraction pawl 410 to swing, thereby causing the active pawl 49 and the anti-retraction clamping claw 410 to act on the same rotating mechanism. Specifically, the telescopic end of the second telescopic actuator 46 extends and retracts, driving the linkage rod 414 to swing about the transmission shaft 42. The linkage rod 414 drives the corresponding pushing mechanism 411 to swing via two rotating shafts. The two ends of the linkage rod 414 swing in opposite directions. Under the action of the linkage rod 414, the two pushing mechanisms 411 also swing in opposite directions. Among them, when the first pushing mechanism pushes the active pawl 49 to engage with the ratchet teeth of the forward ratchet 43, the second pushing mechanism pushes the back-stop pawl 410 to engage with the ratchet teeth of the forward ratchet 43, the active pawl 49 pushes the forward ratchet 43 to rotate intermittently, and the back-stop pawl 410 prevents the forward ratchet 43 from rotating in the reverse direction, thereby preventing the forward ratchet 43 from rotating in the reverse direction when the active pawl 49 is separated from the ratchet teeth of the forward ratchet 43. Similarly, when the first pushing mechanism pushes the active pawl 49 to engage with the ratchet teeth of the reverse ratchet 44, the second pushing mechanism pushes the back-stop pawl 410 to engage with the ratchet teeth of the reverse ratchet 44, the active pawl 49 pushes the reverse ratchet 44 to rotate intermittently, and the back-stop pawl 410 prevents the reverse ratchet 44 from rotating in the reverse direction, thereby preventing the reverse ratchet 44 from rotating in the reverse direction when the active pawl 49 is separated from the ratchet teeth of the reverse ratchet 44.

[0068] The universal rod library for drill and anchor rods also includes a limit frame 413, and the first limit axis and the second limit axis are installed at both ends of the limit frame 413. The first limit axis and the second limit axis are connected to the support frame 41, and the first limit axis and the second limit axis are respectively located on the opposite sides of the first push rod 4111 and the second push rod 4112. The first limit axis and the second limit axis are respectively used to limit the maximum swing range of the first push rod 4111 and the second push rod 4112.

[0069] In this embodiment, the second telescopic driver 46 is an oil cylinder, and may also be an air cylinder or a telescopic rod, as long as it can drive the linkage rod 414 to swing.

[0070] like Figure 1 As shown, the placement mechanism includes at least two spaced-apart rotating disks 3 and a connecting shaft 2. The rotating disks 3 are uniformly circumferentially provided with placement slots for receiving the rods 7. Adjustment blocks are provided within the placement slots to adjust the slot size to accommodate rods 7 of varying diameters. At least two rotating disks 3 are mounted axially in the middle of the connecting shaft 2. A transmission shaft 42 is drivingly connected to one end of the connecting shaft 2. A retaining plate 5 is mounted on the other end of the connecting shaft 2 to axially limit the rod 7 and prevent it from falling.

[0071] When the present invention is used, when the rotating disk 3 needs to be rotated forward from one placement slot position to the next or several placement slots, the telescopic end of the second telescopic driver 46 is extended to drive the linkage rod 414 to rotate a certain angle around the transmission shaft 42, and the linkage rod 414 drives the corresponding pushing mechanism 411 to swing through the two rotating shafts, so that the pushing mechanism 411 pushes the active pawl 49 and the stop pawl 410 to swing, so that the active pawl 49 and the stop clamp 410 act on the same rotating mechanism for forward rotation, and the telescopic end of the first telescopic driver 45 is extended to drive the active pawl 49 to swing, and the active pawl 49 pushes the rotating mechanism for forward rotation to rotate forward until the active pawl 49 abuts against the first stop block 47, then the rotating mechanism for forward rotation rotates one station, and the stop pawl 410 is used to prevent the rotating mechanism from rotating in the opposite direction. At the same time, the forward rotating rotation mechanism drives the connecting shaft 2 to rotate forward one station through the transmission shaft 42, and the connecting shaft 2 drives the placement mechanism to rotate one station, and so on. When several stations need to be rotated forward, it is only necessary to make the first telescopic driver 45 reciprocate and telescope several times.

[0072] Similarly, when the rotating disk 3 needs to be rotated in the opposite direction from one placement slot to the next or several placement slots, the telescopic end of the second telescopic driver 46 is shortened to drive the linkage rod 414 to rotate around the transmission shaft 42 by an angle, and the linkage rod 414 drives the corresponding pushing mechanism 411 to swing through the two rotating shafts, so that the pushing mechanism 411 pushes the active pawl 49 and the stop pawl 410 to swing, so that the active pawl 49 and the stop pawl 410 act on the same rotating mechanism for reverse rotation, and the telescopic end of the first telescopic driver 45 is shortened to drive the active pawl 49 to swing, and the active pawl 49 pushes the reverse rotating rotating mechanism to rotate in the opposite direction until the active pawl 49 abuts against the second stop block 48, then the reverse rotating rotating mechanism rotates one station, and the stop pawl 410 is used to prevent the rotating mechanism from rotating in the opposite direction. At the same time, the reverse rotating mechanism drives the connecting shaft 2 to rotate in the opposite direction by one station through the transmission shaft 42, and the connecting shaft 2 drives the placement mechanism to rotate in the opposite direction by one station, and so on. When several stations need to be rotated in the opposite direction, the telescopic end of the first telescopic driver 45 only needs to be reciprocated and telescoped several times.
